INCI: SOPHORA JAPONICA FLOWER POWDER
A gentle botanical powder rich in antioxidants that may help calm skin and protect against environmental stressors, though research is still emerging.

What it is
Sophora japonica flower powder is a finely ground botanical ingredient derived from the blossoms of the Japanese pagoda tree (Styphnolobium japonicum). It contains flavonoids like rutin and quercetin, which are known for their antioxidant and anti-inflammatory activity.
How it works
The flavonoids in sophora japonica flower powder help neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. Its anti-inflammatory compounds may also calm irritated skin by reducing the production of pro-inflammatory signals. When applied topically, it forms a protective layer that can help shield the skin from environmental aggressors.
